Sparse approaches for the exact distribution of patterns in long state sequences generated by a Markov source [PDF]

, 2012
We present two novel approaches for the computation of the exact distribution of a pattern in a long sequence. Both approaches take into account the sparse structure of the problem and are two-part algorithms.

Obtaining exact value by approximate computations [PDF]

Science in China Series A: Mathematics, 2007
Numerical approximate computation can solve large and complex problems fast. It has the advantage of high efficiency. However it only gives approximate results, whereas we need exact results in many fields. There is a gap between approximate computation and exact results.

Exact and Asymptotic Conditions on Traveling Wave Solutions of the Navier-Stokes Equations

, 2009
We derive necessary conditions that traveling wave solutions of the Navier-Stokes equations must satisfy in the pipe, Couette, and channel flow geometries.

Treatment Decision‐Making Roles and Preferences Among Adolescents and Young Adults With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Decision‐making (DM) dynamics between adolescents and young adults (AYAs) with cancer, parents, and oncologists remain underexplored in diverse populations. We examined cancer treatment DM preferences among an ethnically and socioeconomically diverse group of AYAs and their parents.

Second Rényi entropy and annulus partition function for one-dimensional quantum critical systems with boundaries

SciPost Physics, 2022
We consider the entanglement entropy in critical one-dimensional quantum systems with open boundary conditions. We show that the second Rényi entropy of an interval away from the boundary can be computed exactly, provided the same conformal boundary ...

Exact ground state Monte Carlo method for Bosons without importance sampling

, 2009
Generally ``exact'' Quantum Monte Carlo computations for the ground state of many Bosons make use of importance sampling. The importance sampling is based, either on a guiding function or on an initial variational wave function.

The exact (up to infinitesimals) infinite perimeter of the Koch snowflake and its finite area [PDF]

, 2016
The Koch snowflake is one of the first fractals that were mathematically described. It is interesting because it has an infinite perimeter in the limit but its limit area is finite. In this paper, a recently proposed computational
